The wars in Iraq and Afghanistan have produced a generation of American veterans with physical or psychological ailments. But as The Nation's Joshua Kors has reported in his series on veterans healthcare over the last three years, returning vets aren't always given the care to match their service. In "Disposable Soliders," Kors' cover story last month , he tells the story of Sgt. Chuck Luther, who was wounded by mortar fire in Iraq but pressured to sign papers saying his injuries came from a pre-existing "personality disorder." In this interview  with PRI/BBC's "The World," Kors talks with reporter Marco Werman about the status of Luther's case, and the ongoing effort to win back healthcare for misdiagnosed veterans.
